Improved Grab (Ex): To use this ability, the hangman tree must hit a Large or smaller opponent with its vine attack. If it gets a hold, it can constrict. Constricted foes will be swallowed.

A single attack with a slashing weapon that deals at least 10 points of damage severs a vine (AC 15).

Constrict (Ex): A hangman tree deals 2d6+12 damage with a successful grapple check against Large or smaller opponents. Because it seizes its victims by the neck, a creature in the hangman tree's grasp cannot speak or cast spells with verbal components.

Swallow Whole (Ex): A hangman tree can try to swallow a Large size or smaller opponent by making a successful grapple check. The swallowed creature takes 2d6+12 points of crushing damage per round plus 1d6 points of acid damage from the hangman tree's interior. A swallowed creature can cut its way out by using claws or a Small or Tiny weapon to deal 25 points of damage to the interior (AC 20). Once the creature exits, contraction closes the hole; another swallowed opponent must again cut its own way out.

The hangman tree's interior can hold one Large, two Medium-size, four Small, eight Tiny, sixteen Diminutive, or thirty-two Fine or smaller opponents.

Hallucinatory Spores (Ex): A hangman tree can release a cloud of hallucinatory spores that will cause all creatures within 50 feet to make a Will save (DC 18) or believe the tree to be of some ordinary sort. A creature affected will have no interest in attacking the hangman tree for 3d6 minutes, unless the hangman tree attacks first.

Vulnerabilities (Ex): Electrical attacks deal double damage to the hangman tree; cold-based attacks will paralyze the tree for 1 round per caster level; darkness causes it to act as if affected by the slow spell.

Fire Vulnerability (Ex): A hangman tree takes double damage from fire attacks unless the attack allows a save, in which case it takes double damage on a failure and no damage on a successful save.

Blindsight (Ex): Hangman trees have no visual organs but an ascertain all foes within 30 feet using sound, scent, and vibration.

Plant: Immune to poison, sleep, paralysis, stunning, and polymorphing. Not subject to critical hits or mind-influencing spells or effects.

Skills: A hangman tree receives a +16 racial bonus to Hide checks made in forested areas.
